Sharing and integrating geospatial resources (geo-data and geo-processing) in opening Web environment is a challenge for GISystem. This paper discusses a geospatial information processing concept model complied interoperable system framework and an implementation approach for accessing geospatial information openly by chaining individual service module to assemble complex geospatial processing and...
The definition of advanced and distributed management frameworks is one of the key research issues that still need to be addressed in the network and service management research field. As part of this effort, the use of Web service technologies provides some advanced features such as improved interoperability and flexibility. This paper describes the main requirements and key components of a Web service-based...
